To aZZ whom it may c m-em: V

Beiitiknown that I, EDWARD F. DUDLEY, acitizen of the United States, residingat Oak Park, in the county of Cook and State t of lllinois, have invented certain new and useful Improvements in Registration-Feed, Board-Operating Mechanisms, of whichtl e following is a specification.

My invention'concerns anovel type of op- 1 era-ting or actuating mechanism for the feed or registration boards or platforms of printl ng-presses or similar machines, wherein the movenientbfthe board registers the sheet borne-by it with or causes its edge or edges ge one or more suitable stop or abutment gauges or guides. y

'In printing-presses it is customary to em-- ploy a plurality of front guidesjor gauges againstwhichthe forward edge of the sheet is brought to bear and aside gauge or guide employedin a similar way for the corresponding edge of the sheet, whereby the latter is shifted" into proper and correct position relative to the impression cylinder preliminary to 'itstemporary gripping or fastening to the latter durin'gthe printing op eration. f Insuchinachine's' it is"u sual.to have side gauges or guides at] opposite sides of the board with sultableoperating means, where} by either side edge-bf thesheet may be brought into accurate and true register'with its corresponding guide. I

1 Such capability of shifting the sheet laterally into registerwith either one of the two opposite side guides or gauges is par ticularly' useful when sheets are printed on both sides'enabling'the registration to take effect in'both printing operations with respect to the same edge of th'e'sheet.

The present invention} pertains to i n provernents .in the "means for moving j the 7 feed or registration board to carry the'sheet 7 against the proper guide and concerns more particularly improvedinstrumentalities for modifying onchanging the actionof such board actuating mechanism whereby it may e register the sheet with either of'opposedside guides. In the accompanying shown a desirable and convenient embodiment of such reversible registration-board the other side guide;

one of the pair drawing 1 have operating mechanism, the same reference characters applying to like, parts throughout the several views.

Inth'e drawing: y Figure 1 is a plan view of the actuating mechanism for the, registration board, the side guides being illustrated, but the board itself isnot shown;

Figure 2 is a similar view with the ele. ments of the mechanism in a different position and adapted to feed the paper sheet to Figure 3 isa fragmentary end elevation of the complete appliance illustrating more specifically the meansemployed for reversing; the operation-of the board;

figure 4 is a vieW similar to Figure 3 with the parts coupled up to register the sheet with the opposite side guide; and

Figure 5 is an enlarged plan detail View of such reversing means.

As will be readily seen from the drawing,

the appliance includes a sloping or inclined bodily-movable registration-board or feedplatform 11' mounted for movement on the top of a hollowshell or casing 12 internally supplied WitlI'CI'OSS webs or ribs 13 and 14;.

The'paper sheets are delivered to the top surface of such board by a reciprocatory suction-feeder 15, mounted on power-actuated bent rock-arms 16, which picks up the top sheets in succession. from a stack or pile, not illustrated, and conveys or transports them one by one 'tdand drops them on to the board, the suction of the feeder to control its sustaining effect on the sheet being governed by a valve of any approved form not shown.

The sheet having been delivered to or deposited on the board, the latter moves in a general oblique direction to register it with one or'more front gauges'l? and with either one of two opposite side gauges 18 and 19 depending upon which side of the sheetis to be registered.

To effect this result, mechanismis provided to move the board andit's sheet in the general diagonal direction specified, whereby the front edge of the sheet is first brought against the gauge or gauges 1'7. and then one side edge is shifted into contact with one or the other of the side gauges 18 and 19, as

ating mechanism whereby either side guide or gauge may be rendered operative.

It is desired to give the board a bodily movement first forwardly and then laterallyor transversely without wholly stopping its forward travel whereby to assure the maintenance of contact of the edge ;ot'

the sheet with the front gauge during the securing of its register with the side gauge.

To this end a parallel-motion mechanism is supplied comprising a suitably-guidec'l sliding rack 1 reciprocated by an oscilla- 'tory" gear 22 rockingly mounted in a bearing in the web '13. Such rack is provided with two sets or groups ofsupplementa'lior auxiliary teeth '23 and 24; in mesh respectively with properlymounted oscillatory gears 25 and 26 each equipped with an arm 27 having at its end an upstanding pin 28 with a pivotal mounting in the feed or registration board.

At its opposite side gear 22 coacts with another small gear 29 supplied with a like arm 27 having a pivotal connection at its end with the board, the teeth of such gear being in mesh with those of a rack 31 which at itso'ther end 0 )erates a ear 32 likewise provided with an arm 2? and its pivot pin 28.

f Obviously, the oscillation of gear 22 will simultaneously rock all four a-rms'27 thereby moving the board i a parallel-motion man-- ner first toward the .front gauge or ga-iugre-s andfthen toward one ofthe side gauges. I

v To operate-gear 22 and the elements above described coupled to or affiliated with such gear, it'is equipped with an arm 33 connected by a link 3% to one arm 35 of a threearmed lever 35-3'7-38 fulcrumed at 36 and supplied near the ends of its two opposite arm portions 37 and 38 with outstanding pins or lugs 39 and 41-, either one of which is adapted and designed to fit inan aperture'or bearing in the upper end ofan upright link l2 p-ivotal'lyconnected at its lower end to an oscillatory arm 43 on a rock-shatt 14, the link 42 being pulled toward the lever by a *coiljcontractile, spring 45 having one end connected tohthe link and its other end secured to any convenient and suitable part of the machine framework.

vVhen link 42 is connectedito the pin 39 of arm 37, being held against the arm by the pulling action of spring 45', it is designed by its lengthwise strokes to oscillate the pluralit-y of arms 27 from their original positions as shown in Figure 1, down about 90 degrees and then back to 'their initial posi- "tions', in so doing operating the fboardan the manner described to register its sheet with both the front and side gauges.

Under these circumstances the side gauge 18 only is operative.

If, insteadolf using gauge 18 it is desired to employ the other side gauge 19, 'linik 42'is slipped off of pin'39 against the action of springl'o, the lever 35-37-38rocked onits fulcrum sulliciently to permit the application of the link to the other pin 41, and the link so coupled up to the lever, such turning of the lever having rocked the several arms 27 into the positions shown in Figure 2 ready to carry theboard in a direction to register the sheet with the one or more front gauges and the side gauge 1'9.

arms27 from their initial positions depicted in Figure 2 to positions about 90 degrees therefrom and back again, the registrationboard movingcorrespondingly and carrying its sheet into register with the front gauges and the side gauge 19.. r f

The simple means illustrated and described are e'll ective in operation and may be easily actuated, or modified to change the mode of action of the machineU-The mere movement of the parts to permit the coupling of the elements together assures that the members which directly Qmove the 'board will be incorrect position for doing the work they are designed to perform. The invention is not necessarily limited-to this particular embodiment but 7 comprises all changes fairly falling within the scope of the appended claim defining'the invention.

I claim: s g

In a'sheet-registration appliance of the character described'havingin movable registrati-on-board adapted to bear the sheet, operating means for said board including a lever having pins outstanding from its side on opposite sides of its fulcrunnan apertured link designed to actuate said lever by receiving the oneor the other pin in said aperture, and a spring yieldingly pulling said link toward said lever to maintain o.p'erative theipin and hole connection between the parts, whereby a selective registration, movement of the boa-rd may be had'by'rendering the oneor theother connection opera t-ive between the link and lever, substantially as described; 7 r
